While I denounce any unlawful acts towards anyone or any group in general, you do realize that Islam (a socio-political philosophy, not a religion) in and of itself is contrary to our way of life and is sworn/ ordered to either covert or subdue us by supposed divine dictate? You think they care about such sympathy when one of them butchers non-islamic types?
